Anyone use ExchB yet?

[bbit]

At least they are in the U.S. Anyone have any problems with them? or everything good?

Has anyone done a write-up on all the different features and differences between all the exchanges?

Mt. Gox, TradeHill, bitcoin7 and the others ....

[Alphonso Bedoya]

Yes, I use them, along with MtG and TH.  It seems to work very well. They respond promptly to emails. Another plus to me is that the layout gives me all my info on one page for trading.  Thumbs up.
